| Abstract: |
How our ideas about the nature of the p-mode oscillations have
evolved will be discussed first. In the beginning, two basic models
were considered: the effect of the acoustic cutoff frequency on
mode excitation and propagation and the existence of a resonant
cavity. The issue with the latter was the location of the cavity.
Next the evolution of our ideas on the excitation of the modes will
be described. Initially, the oscillations were thought to be driven
by convection. Then the possibility of overstability was explored.
Now we are back to the initial idea of stochastic excitation by
convective turbulence. |
